Happy Wash is a car wash company operating in Adelaide. There are about 50 Happy Wash outlets, found at some, but not all On The Run petrol stations.

The DealIf you regularly pay for a car wash pick up a loyalty card when you use Happy Wash. Get the date filled in on the card each time you pay for a wash. The deal is you pay four car washes and the fifth one is free. The free wash is the basic $9.95 wash. If you wish to upgrade your free wash you can but you have to pay the extra amount. Therefore if you wanted the Soft Wash Ultimate Wash which normally costs $19.95 you would pay the extra $10.
